Like an Olympic sprinter with his head stuck in a stairway banister, vehicle engines desperately need lubrication if they're going to run properly. Oil up with today’s Groupon: for $20, you get an oil change (a $36.30 value), tire rotation (an $18 value), and 19-point inspection at Davis Import Auto Service in Davis (a $54.30 total value).

The owner of Davis Import Auto Service channels more than 30 years of repair experience to keep vehicles roadworthy with a wide variety of routine services and repairs. The buggy-surgeons begin the maintenance with a complete oil transfusion, collected from the engines of brave donor cars. Each tire is then relocated by the technicians, promoting harmony through even wear and quelling disputes about who gets to ride on the front wheels. A 19-point inspection follows to ensure everything is shipshape under the hood and chassis. The entire process takes about 45 minutes, giving patrons ample time to meet the shop’s resident dog, Roxy, who loves biscuits and can change a fuel filter in 20 seconds flat.
